LamellenFix®

LamellenFix® is a fixing system specifically designed for the secret-fixing of timber louvres and fins on various façade substrates. This quick and visually appealing way to mount timber slats was developed, patented, and manufactured in Austria, by SIHGA. The innovative fixing system meets the highest European quality standards and offers excellent durability and stability for demanding architectural projects.

How does it work?

The system is designed with two identical parts that can be pre-assembled on the timber slat and the substrate. This pre-assembly ensures accuracy and reduces potential errors during fitting. The connectors are secured using a locking screw, which provides equal load distribution across the mounted fins. This guarantees the stability and structural integrity of the system, especially in larger-scale applications.

Designed and manufactured in Austria from anodised aluminium, the LamellenFix® system is rust-free, dimensionally stable, and built to last. This ensures the system remains functional and aesthetically pleasing throughout its service life, even in challenging weather conditions. Due to its robust and reliable design, LamellenFix® is particularly suited for commercial projects that require large timber fins over 60x80mm offering a secure, aesthetically pleasing, and structurally sound secret-fixing solution.
